GRAIN DOOR.

Application filed December 4-, 1926. Serial No. 152,611.

This invention appertains to grain doors the or gates for railroad boxcars, vehicle bodies and the like and the primary object of the presentinvention is to provide a grain gate or door which can be used a greatnumber of times without injury thereto, thereby resulting in a saving oflumber and money as well as a saving of time and effort in removing thedoor or gate from its operative closed position. I

Another object of the invention is the provision of novel means forapplying the gate in place, whereby the same can be effectively reused,the gate having pairs of swinging apertured steel plates at each endthereof for receiving the holding nails, the plates being so arranged asto be swung todifferent positions for different widths of door frames.

A further object of the invention is the provision of a novel grain dooror gate including inner and outer skins or sections, which are soarranged as to provide a leak proof construction the ate also beinorovided .b N a.

with a novel outlet closure. r

A further object of the invention is the provision of a novel lock forthe closure and novel means for permitting a car seal to be used withthe lock or closure whereby tampering with the latch or lock can bereadily discovered. 1

A still further object of the invention is to provide a leak proof graindoor or gate of the above character, which will be durable and efficientin use, one that will be simple and easy to manufacture and one whichcan be placed upon the market and incorporated with a box car or vehiclebody at a small cost;

With these and other objects in view, the invention consists in thenovel construction. arrangement and formation of parts, as will behereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which drawings:

Figure 1 is a fragmentary side elevation of a box car showing ourimproved door connected therewith,

Figure 2 is a top plan view of the door showing the same in position ona box car, the car being shown in horizontal section,

Figure 3 is a central horizontal section through the improved door,

Figure 4 is a fragmentary elevation lookigg at the inside f he d or showng ne f and swinging attaching plates connected therewith,

Figure 5is a detailed horizontal section taken on'the line 5-5 of Figure1, and Figure 6 is a detail vertical section through the latch taken onthe line 66 of Figure 1,

Figure 7 is an elevation of the gate showing the same in use on a wagonor truck body, and V Figure 8 is a plan view of the same.

Referring to the drawings in detail, where in similar referencecharacters designate corresponding parts throughout the several views,the letter A generally indicates the improved grain door or gate and B.a box car with which the same can be associated. The box car B. is ofthe conventional type and includes the usual side wall 10 having thedoor opening 11 and the side frame bars 12. The gate A is preferablyconstructed from wooden strips and includes outer and inner skins orsections 13 and 14. It is to be noted that the strips 15 of the outerskin 13 run horizontally while the strips 16 of the inner skin runvertically. This provides a grain proof door or gate.

The door or gate preferably includes upper and lower sills or bars 17and 18 andthese bars or sills extend beyond the front face of the dooror gate. As shown the ends of the sills are notched as at 19 to provideshoulders 20. It is to be noted that the longitudinal walls oft-henotches 19 are flush with the outer face of the outer skin 13 of thegate. This allows the face of the door to be fitted flush up against theframe bars 12 of the 'door opening.

On the inner face of the door at each end thereof we provide pairs ofattaching plates 21 and these plates are pivoted intermediate their endsto the door or gate by means of suit able bolts 22. The door itself oneach side ofthe pivot point of the bolts is provided with spacedopenings 23 and one end of the attaching plates 21 is provided with anail receiving opening 24 which is adapted to he brought intoregistration with either one of the openings and by placing nails 25 inthe openings, the gate or door can be quickly applied to differentwidths of frames and the attaching plate 21 forms means for receivingthe nails for preventing the splitting of the gate or door andfacilitate removal of the fas tening elements from out of the doorframe.

The provision ot'the gate or door with the pairs of relativelyspaced-openings23,,permits the door to be nailed to the "uprights ofdoor openings of diiferent widths. When thegate or door-is-appliedtoa-door opening wider than -:the i one illustrated in thedrawings, certain of the openings 28 will be located outwardly beyond orbelow the-uprights. These openings will becloscd bythe plates 21 toprevent the passage of water and ai t ough t em,,and,.the' ai w Pa sthrough the openings into the plates and the emain ng open ng nthegrdoor.

"In accordancewithjtliis invention ,the gate orv door at a centralpointiisprovided with, an

' enlarged outlet opening 26, which is adapted to be closed byz asuitable c'losure 27. This urei 27 i orme o er appi,ng boar the same asthe body portion of the gate. This s re 2 is onnec ed to th ga e yuse ftabl h nges28- n rde t ma ntai ,Q1 S 1re27' in. its

' normal ,closed position we provide: a latch V I otedLlockingjplate 33which,serves as means torpreven'ting the rocking of the latch bar from.outof engagement with the, keeper plates 51 andf32. This locking ,plate33 is adapted to, receive aistaple 34: rigidly .6011- nectedwith thegate ordoorand a suitable tapered pin'35 is provided for fitting in thestaple 3.4 whereby swinging movement of the locking plate 38 will beprevented and consequent swinging movementof the latch T bar 29. 'Ifpreferredthe tapered lockpin dl'rcari'v be connected with the frame ot'adoor by suitablefflexible means such as a cha1ni36. [T he lower free endof thispin has a trans- 7 Verse opening37' for the reception of a carseal 38. i

:"Iti's to ,be noted that the staple 34 .is carried. by an angularattaching base .plate"38 the'lower portion of which is arranged inhorizontal plane and-provided with an opening in alinement',wi th.thestaple 34 for receiving'thelower endof the tapered pin'35.

'7 -Fromthe foregoing descriptionQit can be seen that a grain car doorhas been provided which can be easily applied to and easily removedwithout appreciableinjurylto the door or door frame.

In Figures 7 and 8 we have shown the gate applied toa vehicle body Cwhich-can be considered either;.-as,-a ,wagon ortluckiibody. This bodycan be of any conventional character-and is provided with upright stopcleats 40 at the rear endthercof against which the gate is adapted tobe'fitted. The gate in this instance is of substantially the same.eonstruction as thegate or door previouslyidesigned and thereforeadetail description thereof will notbe here given.

Changes in details may be made without departing from the spirit orscope ofythisinvention,-but what we claim asnQ lis:

.1. The combinationwith a car havingan opening and provided with spaceduprights at the sides of the opening, of a removable closure, includinga body, sills secured to the upper and lower ends of the body andextending beyond thefront or outer side of the body, the sills beingprovided at their ends with notches receiving the uprightsand ,deepenough to permit the outer side ofthe closure to lie in full abuttingcontact witlrthc inner sides of the uprights,.and retaining'elqmentspassing through the body and engaging the uprights.

2. A removable closure for an opening in a car having uprights ,at thesides of the opening, comprising abody adapted to rest in full abuttingcontact, with the inner sides of the uprights and provided with pairs ofspaced. openings. the openings of each pair being horizontallyalignedand one opening of each pair'being arranged directly in rear ofthe-uprights, the other openings bein rarranged'laterally beyond theuprights, plates greater in length than the distance between theopenings and pivoted centrally between their ends to the body at pointscentrally betwcenthe openings, the plates 'closing;the openings,laterally beyond the uprights and provided with openings registeringwith the openings directly inrear of the uprights, and elements passingthrough the openiugsimthe plates and the registering openings in thebody and engaging the uprights.

In, testimony w iereof we afiix our signatures.
